Cisco Webex Video Platform Version 2 Known Issues


This section applies only to Webex Meetings sites that have the Media Resource Type list available in the Cloud Collaboration Meeting Room site options. Contact your administrator for more information.

H.264 video codec required for content sharing

Content sharing is only supported using H.264 video codec. Older video systems that do not support H.264 codec will not be able to do content sharing.


Environments newly implementing Cloud-based services, or reviewing integration with Cloud-based services, should ensure that their Telepresence endpoints are sending High Definition Content. This typically includes setting endpoint’s Content Input Sources to Optimal Definition "High", along with ensuring the appropriate bandwidth is set to accommodate simultaneous HD-Level H264 main video and content. Please review the relevant TC or CE endpoint Administration Guide for Optimal Definition and Resolution-Bandwidth settings.

In-meeting video thumbnail experience

Any cascades in Webex Meetings are limited to up to six streams at a time in either direction. For example, Webex Meetings participants only see up to six video streams of Webex Video Platform users connected through TelePresence, Webex Cisco Webex Teams, Webex Room and Desk Devices, Skype for Business, and other SIP or H.323 devices connected to the meeting. Likewise, Webex Video Platform users only see up to six participants using Webex Meetings apps including apps for desktop, mobile, and web. Also, any participants that are connected through Webex Video Mesh nodes have the same limitation between their specific Webex Video Mesh node and devices or apps that are connected directly to the Webex cloud or other Webex Video Mesh nodes.

Cisco Webex Video Platform Version 1 Known Issues

Call My Video System

The option to Call My Video System may fail if attendees are required to press '1' and no RMS or Traversal Licenses are installed on the Customer Expressway-C and Expressway-E pair.

Video Systems Unable to Join Webex Events on FedRAMP

Video systems are not able to join Webex Events on the FedRAMP platform because the FedRAMP platform is currently running Video Platform 1 at this time.

Display names

Display names for video conferencing system users are not visible in the Webex meeting video window. This issue will be addressed in a future update.

Leaving and reentering a Personal Room

Sometimes, when hosts end a Webex video platform version 1 meeting by leaving their Personal Room and then reentering their Personal Room within a few seconds, they may hear an audio prompt about an invalid meeting. If this happens, the host should hang up and wait a few seconds before redialing the Personal Room.

12-hour limit

A scheduled Webex video platform version 1 meeting can't last for more than 12 hours. Hosts and participants can reenter the meeting, or can schedule a new one.

Telephony service provider (TSP) audio

For users on Webex Meetings sites that utilize TSP audio conference bridges, video systems will not be able to join meetings until the meeting host has configured the toll phone number for their TSP audio service provider. To avoid this problem in a meeting, we recommend that hosts specify the toll number of the TSP audio service in their account preferences.

Due to some dial-out sequences having multiple steps and longer prompt durations that cannot be interrupted, it may take a while before audio from Webex Meetings users joining through phones can be heard by video systems and video systems can be heard by phones. During this time, users who have joined from video systems have no indication that their audio is not being heard by users who have joined using Webex Meetings. To avoid this problem, all participants should wait until the TSP audio dial-out sequence is complete, which is indicated by phone handset icons appearing next to participants' names in the participants list.

Truncated display names on video systems

If there is network bandwidth degradation on a user's video system, its video resolution may be reduced to a size that better accommodates the current network conditions. In that scenario, the display names of participants may appear truncated in the video endpoint active presence view. This is due to the lower resolution video for the video stream, which has a limited number of pixels to display the participant name.

In-meeting video experience

Starting in WBS33, Webex Meetings apps default to a filmstrip layout which requires that each participant be able to send thumbnail-quality video streams. Since Video Platform Version 1 only supports sending the active speaker video to Webex Meetings, Video Platform users will not have their video displayed in the filmstrip.

iOS meeting participants are able to view the video stream from video systems in 1 × 2 portrait mode only.

Video systems joining without encryption

If attendees join a meeting using video systems that do not setup encrypted signaling links or use encrypted media links, the meeting cannot be considered fully secured, since there are other devices whose connections cannot be secured.

Call leg security

The encrypted meeting status icon on video systems utilizing Telepresence Interoperability Protocol (TIP) or Call-Info security attributes does not reliably indicate the encryption status in meetings. Even when all call legs are encrypted, this icon may still indicate an unencrypted meeting.

Support for Microsoft Lync or Microsoft Skype for Business Applications

  • Content that is shared in a Webex video platform version 1 meeting is transcoded into the main video channel for users on Lync and Skype for Business clients

  • Clients using RTV video codec is not supported, including Lync 2011 on Mac OS.

  • For users registered to a Lync or Skype for Business server, Polycom video devices aren't supported.

  • To ensure 2-way video in a meeting, users must select Video and then select Start Video on the application before joining the meeting.

  • After joining the meeting, users may need to select Start Video one more time.

Join meetings by dialing an IP address

Known Issues for Using Webex Meetings video platform version 1 with Cisco Teams

  • Cisco Webex Teams and Mozilla Firefox

    When Cisco Webex Teams users in Mozilla Firefox share their screen, Webex users see a black screen, instead of the shared content. When Webex users share their screen, Webex Teams users in Firefox can see the shared content.

  • Video Call-Back to Cisco IP Phone 8800 Series Video Phones Registered to the Cisco Teams Calling Service

    When you initiate a video call-back from the meeting to Cisco IP Phone 8800 Series Video Phones registered to the Webex Teams Calling service, where the site is configured to require DTMF key 1 to connect to the meeting, this connection fails. The workaround for these devices is to disable the requirement to enter DTMF key 1 to connect to meetings.

  • Sending video from Webex applications to video conferencing systems or applications

    A Webex Meetings video or CMR Hybrid meeting always starts at the best video resolution between video systems and the Webex Meetings application. If high-definition video is available, it is available to all participants. If any participant on the Webex Meetings side experiences poor network conditions, the resolution between video systems and the Webex Meetings application downgrades to accommodate that participant. As a result, video resolution will also be poor for all other participants. The minimum bit rate a Webex Meetings application must process from the Webex Cloud to be able to receive both video and application or screen sharing (formerly called "desktop sharing") content is 1.2 Mbps. Less than that results in the Webex Meetings application showing only the shared application or screen.

    For information about recommended bandwidth configuration settings for Webex video platform version 1 meeting, see the Cisco Webex Network Bandwidth White Paper.

    For information about recommended bandwidth configuration settings for CMR Hybrid meetings, see "Prerequisites" in the "Cisco Webex Features and Important Notes" chapter and "Tips for Troubleshooting Low Bandwidth with the Webex Meetings application on Windows or Mac" in the "Troubleshooting" chapter of the CMR Hybrid Configuration Guide on the Cisco TelePresence Management Suite (TMS) Configuration Guides page. For additional information, refer to the Cisco Webex Network Bandwidth White Paper.

  • Presentation and data sharing quality

    If you do not have adequate bandwidth, your presentation and data sharing in Webex Meetings video and CMR Hybrid meetings can degrade to XGA (1024 x 768 resolution) and 5 frames per second (FPS). On TelePresence systems, users see a "letterbox" format.

    Assuming all Webex Meetings applications have at least 2Mbps bandwidth, users in the meeting can enjoy 720p content sharing at up to 5 FPS.

    If Webex Meetings applications have at least 3-Mbps bandwidth, the content share quality is 1080p at 3 FPS.

  • Full-screen video view

    When presenters switch to full-screen video view while sharing their screen, application, or document, sharing is paused on the attendee side (the last-shared screen freezes). When the presenter exits full-screen video view, sharing automatically resumes.

    Attendees stay in full-screen video view when the presenter stops sharing and automatically exit full-screen video view when the presenter starts sharing again.

    If the Webex Meetings desktop application has two monitors, users can display a full-screen view on one monitor and full-screen or application sharing on the other monitor by dragging the video window to the other monitor and selecting the "View all participants in full-screen view" icon.

  • Presenter may unintentionally disable video for all participants

    If a Webex Meetings user who is the presenter in the meeting unchecks the Video option in the Meeting Options dialog box, video is disabled for all meeting participants, whether they joined from a Webex meeting application or from a video conferencing system. To restore video for all participants, the meeting host or current presenter should check the Video option in the Meeting Options dialog box.

  • Other teleconference audio

    The audio connection option Other teleconference audio is not supported for CMR Hybrid and Webex Meetings video conference meetings.

  • Telephony service provider (TSP) audio accounts

    For some telephony service provider (TSP) audio accounts, if a host with a TSP account schedules two adjacent CMR Hybrid or Webex Meetings video conference meetings, with the second one scheduled to start immediately after the first one ends, and if the TelePresence scheduling system automatically extends the first meeting past the scheduled end, the second meeting will end automatically because the same TSP audio account and host access code cannot be used for both meetings at the same time.

    To work around this problem, hosts can set up two different TSP audio accounts with different host access codes, and use one account for the first meeting and the other account for the second meeting. Another option is for the administrator to turn off the option for the TelePresence system that automatically extends the meeting.

  • Webex Meetings features

    If you are hosting a meeting that includes video systems, the following in-meeting features are unavailable:

    • Whiteboard

    • Document sharing

    • Polling

    • File Transfer

    • Chat (with TelePresence room participants)

For a list of compatible video systems and applications see Webex Meetings Video Compatibility and Support.

CMR Hybrid Integration Known Issues

The following issues apply to joint meetings with Webex Meetings and TelePresence in the CMR Hybrid solution:

  • Participant list

    • The Webex Meetings host in a joint CMR Hybrid meeting with Webex Meetings and TelePresence is not able to see a complete list of all Webex Meetings and TelePresence participants.

    • TelePresence participants are listed as "TelePresence Systems" in the Webex Meetings Participants list of a CMR Hybrid meeting.

  • Exceptions to a recurring meeting series using Webex Meetings Productivity Tools

    Although recurring meeting exceptions for CMR Hybrid meetings are now supported in Webex Meetings Productivity Tools. "Orphan" meetings are not yet supported. For example, you cannot add a Webex meeting and TelePresence rooms to a single occurrence of an Outlook-only meeting series. If you want to make these features available for a single occurrence, make the whole series a Webex Meetings and TelePresence meeting.

    Edits to a meeting series with exceptions that were changed before version WBS30 follow Microsoft Outlook's rules, where possible, regarding treatment of the exceptions' properties.

    If a host edits the subject or changes the meeting time of a single occurrence of a recurring CMR Hybrid meeting series by editing it directly in the Microsoft Outlook calendar, and then removes Webex Meetings from the entire series, the Webex meeting information still appears in the exception meeting.

    If the host scheduled a recurring CMR Hybrid meeting series, and the date of the first occurrence has passed without that meeting being started, the host cannot update the date of that individual occurrence. However, the host can change the date for the entire meeting series.

    If you remove the Webex meeting from an individual occurrence of a CMR Hybrid meeting series, you change it to a TelePresence-only meeting. However, the Cisco TelePresence Management Suite (Cisco TMS) still shows Webex Meetings information for that exception meeting.

    If you change all the individual meeting occurrences within a meeting series into exceptions, and you then attempt to add a TelePresence meeting to the entire series, Cisco TelePresence Management Suite for Microsoft Exchange (Cisco TMSXE) assumes the series in the past and does not give adequate warning messages to the meeting scheduler or host. Users can work around this issue by deleting the current series and creating a new series that has TelePresence added, and then editing the exceptions to that series individually, as exceptions, or deleting all the exceptions and creating individual meetings.

  • Making someone presenter

    A TelePresence system becomes the presenter when a VGA cable is connected to the laptop. In a standard Webex meeting, a user has to ask the host to make him or her the presenter. By default, the ability for anyone in the meeting to "grab the ball" or request to be the presenter is enabled for CMR Hybrid users. Starting in WBS29.11, the Anyone Can Share feature allows anyone to share without requesting to be the presenter. This option is also enabled by default for CMR Hybrid users. If you are connected to both Cisco Jabber and Webex Meetings on the same computer and try to share content from Jabber, you get repeating share windows. We recommend that you always share from Webex Meetings if you have both Jabber and Webex Meetings on your computer.

  • Time zone

    The time zone for the Webex Meetings site must match the time zone for the Cisco TelePresence Management Suite; otherwise the meeting time is not synchronized.

  • Leaving a meeting

    Unlike Webex Meetings-only meetings, which have an option to automatically extend if attended by audio-only callers, when all TelePresence endpoints leave a CMR Hybrid meeting, if there are no users of Webex Meetings applications to pass the host role to (or if audio-only endpoints are the only other attendees of a CMR Hybrid meeting), and capacity constraints on the TelePresence Management Suite do not allow the TelePresence side of the meeting to automatically extend beyond the scheduled end time of the meeting, the meeting ends.

  • File sharing and whiteboard sharing

    File sharing and whiteboard sharing are not supported in CMR Hybrid meetings. We recommend that you use screen sharing or application sharing instead.

  • Audio codec

    Cisco recommends the G.722 audio codec on the CMR Hybrid link for the best user experience. The G.711 codec is also supported as an alternative. We do not recommend or support use of the G.729 codec on the CMR Hybrid link.

  • Sending video from Webex Meetings applications to video conferencing systems or applications

    A Webex Meetings video or CMR Hybrid meeting always starts at the best video resolution between video systems and the Webex Meetings application. If high-definition video is available, it is available to all participants. If any participant on the Webex Meetings side experiences poor network conditions, the resolution between video systems and the Webex Meetings application downgrades to accommodate that participant. As a result, video resolution will also be poor for all other participants. The minimum bit rate a Webex Meetings application must process from the Webex Meetings Cloud to be able to receive both video and application or screen sharing (formerly called "desktop sharing") content is 1.2 Mbps. Less than that results in the Webex Meetings application showing only the shared application or screen.

    Attendees stay in full-screen video view when the presenter stops sharing and automatically exit full-screen video view when the presenter starts sharing again.

    If the Mac or PC Webex Meetings application has two monitors, users can display a full-screen view on one monitor and full-screen or application sharing on the other monitor by dragging the video window to the other monitor and selecting the "View all participants in full-screen view" icon.

  • Presenter may unintentionally disable video for all participants

    If a Webex Meetings user who is the presenter in the meeting unchecks the Video option in the Meeting Options dialog box, video is disabled for all meeting participants, whether they joined from a Webex meeting application or from a video conferencing system. To restore video for all participants, the meeting host or current presenter should check the Video option in the Meeting Options dialog box.
